Question

Does aliens are also included in diversity in living organisms

Answer 1

The first aliens that humans encounter won’t be little green men. They will probably be tiny microbes of one color or another — or perhaps no color at all.

Many insist that certain features must be present for any type of life, including aliens. These include an active metabolism, reproduction and evolution. Others add the requirement that life must have cells big enough to contain protein-building machines called ribosomes (RY-boh-soams).

But you may not need to leave our planet to find aliens. There’s the possibility of shadow life on Earth. It could be so strange that it has so far gone unrecognized says scientists

this implies that aliens do share our diversity but we cant see them
